Keyhole hanger 20mm
thingiverse
Needed a hanger to replace some cheap ones that were installed in a mirror. Most of the ones i found on here were too thin as I needed to support a mirror.so I modeled these up in couple minutes in Fusion 360. These will fit a 20mm hole 8mm deep. Used some CA glue to install but epoxy would probably work as well. PLA would probably work but used ABS for added strength given the weight of object I was hanging.
